PLANlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 361,669, dated April 26, 1887.

Application filed August 1, 1885. Serial No. 178,271. (No model.)

To all whom, it mcry concern:

Be it known that I, EDWARD A. BLAKE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wood-PlaningMachines for Electrotypers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertai'ns to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to furnish an improved wood-planer for electrotypers use in which the spindle of the revolving diskshaped tool-carrier is adjustable laterally, longitudinally, and vertically, and the bearings thereof so constructed that the necessityas in the old machine-of putting new Babbitt metal bearings in every now and then is obviated, and in which the devicesfor vertically adjusting the said head are graduated, and otherwise so constructed as to permit of and intelligently indicate any adjustment of the same desired.

In the drawings, Figure 1 is a vertical longitudinal section of the machine. Fig. 2 is a front or face view of my improvements. Figs. 3, 4 are detail views of the same, and Fig. 5 is a detail view showing the mortise in lugs between which the bearings of the spindle are placed.

Reference being had to the drawings, it will be observed that the general principle and construction of my improved machine is the same as in the old kind, viz: it has a table-frame, a bed having a longitudinal reciprocal movement on said frame, anda diskshaped cuttercarrying head suspended over the same, hav ing a revolving motion, which is imparted to it by a spindle, on the lower end of which it is made fast. This spindle is journaled in suitable bearings and is driven through the medium of a belt and pulley.

In the old machinethespindle A isjournaled in immovable bearings with Babbitt metal as an unguent, which, when used for a certain length of time,wear so thatthe cutter-head cuts deeper on one side than the other, thus necessitating rebabbitting every now and then.

In my invention the bearing-standard B is provided with laterally-projecting and parallel lugs a a, which are provided with horizontal mortises on their inner surfaces, correspondingly located. Placed between these lugs, and having tenons on either side which project into the mortises of lugs a, are the brass bearing-boxes C C, which are divided vertically, transversely, and centrally into two parts.

The spindle A is placed between the two parts of the bearing-boxes C, the outer part of which latter is held in place and snugly against the spindle by means of the caps b, which are secured in place by the set-screws b.

The standard B is adjustably secured to the horizontal cross-bars c and d of the rectangular open frame -D by means of the L-shaped irons e e,which are placed against the vertical edges of the said standard and secured thereto by screws 6, which pass through verticallyelongated holes e in the outer arm of irons e, and are secured to lugs f, projecting laterally from the frame D, by means of set-screws f, which pass through the elongated holes f in said lugs f. By loosening the screws 6 and f on one side, and the lower screw, 6, on the other, the standard B can be oscillated laterally slightly, sufficient for all practical purposes.

At the top of standard B, which extends above the upper horizontal bar of frame D, there is a lug, g, projecting laterally in the direction opposite the bearings C. Projected vertically down through lug g, from above, is the screw E, having a balancelever at its top end to manipulate it with, and having a sleeve, G, which is flanged at its upper end to prevent its dropping through the aperturein lug g. Sleeve G is provided with aT-slot, which gives it spring-tension, so that as the screw h; which passes laterally into lug g, bites it, it clamps the screw within its embrace and prevents its being turned. The screw E passes vertically down through a laterally-elongated aperture in the upper horizontal bar of frame D, and through a blind plug, F, which is cylindrical in cross-section, and is inserted from the inside in a corresponding lateral aperture in said bar. Screw E passes diametrically through plug F, and is screw-threaded only in that portion within said plug. This arrangement of the devices, in connection with screw E, permits of the limited oscillation of standard B.

Frame D is pivoted between the posts H, which are secured to the sides of the tableframe of the machine by means of pivotalpins or screws is, secured at about-the center of the vertical side pieces of frame D. Passing from would likewise be dispensed with. Thesta'nd ard B would then be secured directly to frame B by screws 6, passing through verticallyelongated holes in standard B, near its edges. In some machines the general run of the work is of such a character that adjustment of the cutter-carrying head need be onlyin the direction of the length of the machine. In this event the means for adjusting the standard could be dispensed with and the standard itself be made integrant with or rigidly affixed to frame D.

What I claim as new, and desire to secure by Letters Patent, is-

1. In an electrotypers wood planer, the combination, with the horizontally-revolving cutter-carrier head and vertical spindle A,to the lower end of whlch said head is secured,of the standard B, in bearings affixed to which said spindle is journaled frame D, to which the standard is adjustably secured, and posts H,to and between which said frameis pivoted.

2. In an electrotypers wood planer, the combination, with the cuttercarrying head and spindle A, of the frame D, having a longitudinal oscillation, and posts H, to and be tween which said frame is pivoted.

3. In a wood-planer, the combination, with the cutter-carrying head and vertical spindle, of the adjustable standard having lugs a a, which project from both the upper and lower parts thereof, so as to pass on each side of said spindle, and which are horizontally mortised in their surfaces adjacent to said spindle, the

bearings divided vertically into two parts, as.

described, and a cap for confining said bearing between said lugs 11 a and in close contact with the journals of said spindle.

4. The combination, in an eleetrotypers wood plan'er, of the horizontally-revolving cutter-carrier head, the vertical spindle A, to

the lower end of which said head is secured standard B, in bearings secured to which said spindle is journeled L-irons e, as described, and rectangular open frameD, having lugs f, to which said L-irons are adj ustably secured, in the manner set forth. A

- 5. The horizontally-revolving cutter-carrier head, vertical spindle A, standard B, having at its top a lateral lug, g, vertical screw E, passing downward through lug 9 into frame D, and adapted to raise and lower standard B, sleeve G within lug 9, through which said screwpasses having a T-slot therein, as described, and lateral screw h, in combination with said frame D.

6. The combination, with the cutter-carrying head, spindle A, standard B, having alug, g, and capable of lateral oscillation, and screw E, of frame-D,having an elongated screw-hole, and plug F, placed laterally in said frame and tapped diametrically toreceive said screw..

In testimony that I claim the foregoing as my own I hereunto affix my signature in presence of two witnesses.

EDWARD A. BLAKE.
